BAV 99W H6433 Application Field and Working Principle

Introduction

The BAV 99W H6433 is a surface-mount Schottky diode array package that consists of two individual rectifier diode chips in a common package. It is a three-terminal device used mainly in a variety of switching power supply and low voltage circuitry applications. It can be used as a dual rectifier bridge as it contains two independent diodes packaged together in one 3-pin configuration. The BAV 99W H6433 is available in a number of popular sizes such as the SOT-89, TSOP-3 and the QFN packages.

Application Field

The BAV 99W H6433 is typically used in small-size power supplies, such as cellular phones, laptop computers, PDAs, and other portable electronic devices. It can also be used in the general low voltage current-limiting and switch-mode rectifiers applications. Due to its small size, BAV 99W H6433 is particularly suitable for power planes of printed circuit boards and compact power control with small space in the circuit board. This device has a very low forward voltage drop and can also be used for power control and in power bridges which can handle higher current and voltage requirements.

Working Principle

The BAV 99W H6433 works on the principle of rectifying silicon diode. It has two independent diodes packaged into one common package, making it ideal for dual bridge application. It has a low forward voltage drop and can handle relatively high current.As the name suggests, it is a Schottky diode array. Schottky diodes are known for their fast switching characteristics and improved electrical performance over regular diodes, given their small forward voltage drop. This makes them effective rectifiers and suitable for applications that require high-frequency operation and increased power efficiency. The BAV 99W H6433 consists of two individual rectifier diodes in one package where each one of them having a separate Schottky diode. The two Schottky diodes are connected in anti-parallel, with the anode of one diode connected to the cathode of the other diode and vice versa.

Conclusion

The BAV 99W H6433 is a dual rectifier bridge package that is ideal for use in low voltage switching power supply and other low voltage circuit applications. It is relatively small in size and thus can be easily integrated into small circuit board power plans. Being a Schottky diode array, it will provide improved power efficiency and fast switching characteristics, making it suitable for high frequency operation.
